What the bulletin says

DTC C1001:31 and/or U3000:89 may be stored in the IPMA, but may have recently been cleared and stored in the vehicle's history. This may be due to a connection issue between the IPMA Camera and the IPMA. To correct the condition, perform the following service procedure to repair the connection and reset the IPMA.

Read by machine from the document NHTSA serves (15 pages), read Sep 30, 2026. A part number is shown only where it matches Ford’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

While driving on thruway, it began to snow.. One. by one the safety sensors reported failure due to being blocked. Even basic criosese control stopped working. As conditions cleared none of the sensors recovered. I pulled off at an exit to clear any remaining snow that may have been blocking the sensors.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 23-2137 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the TSB 23-2137 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does TSB 23-2137 cover?
The manufacturer filed it against 3 model years: 2023 Ford Mustang Mach-E, 2022 Ford Mustang Mach-E, 2021 Ford Mustang Mach-E. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
